Medicare HOS Instrument

The Medicare HOS instrument consists of three components: the SF-36® Health Survey; questions for case mix and risk adjustment purposes; and questions added by CMS as required by the 1997 Balanced Budget Act. Physical and mental functioning are measured with the Physical Component Summary (PCS) and Mental Component Summary (MCS) scores, which are derived from the SF-36®. If you have any questions, please feel free to contact the Medicare HOS Information and Technical Support Line.

The following Medicare HOS Survey Instruments are available for download:
